TableView not loading cells - ios

Question

My table view isn't loading the custom cells that are put into an array when I do a certain function. I know the the array contains the cells, but am at a loss as to why the cells aren't showing. It did work before but I made a few changes elsewhere in the code and now it does not work. Below is the code where I believe the error might possibly be:
#IBOutlet weak var incomeExpenseTableView: UITableView!
override func viewDidLoad() {
super.viewDidLoad()
incomeExpenseTableView.reloadData()
incomeExpenseTableView.delegate = self
incomeExpenseTableView.dataSource = self
}
override func viewDidAppear(animated: Bool) {
incomeExpenseTableView.reloadData()
}
#IBAction func addButtonPressed(sender: AnyObject) {
let addMessage = SCLAlertView()
addMessage.addButton("Income") {
self.performSegueWithIdentifier("incomeSegue", sender: self)
}
addMessage.addButton("Expense") {
self.performSegueWithIdentifier("expenseSegue", sender: self)
}
addMessage.showInfo("New Entry", subTitle: "Select either an income or expense to add")
}
func tableView(tableView: UITableView, cellForRowAtIndexPath indexPath: NSIndexPath) -> UITableViewCell {
let post = DATA_KEY._loadedPosts[indexPath.row]
if let cell = tableView.dequeueReusableCellWithIdentifier("IncomeExpenseCell") as? IncomeExpenseCell {
cell.configureCell(post)
return cell
} else {
let cell = IncomeExpenseCell()
cell.configureCell(post)
return cell
}
}
func tableView(tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
return DataService.instance._loadedPosts.count
}
func onPostsLoaded(notif: AnyObject) {
incomeExpenseTableView.reloadData()
}
FYI DATA_KEY = DataService.instance
Thanks

Answer 1

if you have a tableviewcell's identifier named "IncomeExpenseCell", the "if let" will always be successful, why using else, you can use as! instead of as?, you don't need 'else' here, and IncomeExpenseCell() maybe will not satisfy your 'cell init'
if let cell = tableView.dequeueReusableCellWithIdentifier("IncomeExpenseCell") as? IncomeExpenseCell {
cell.configureCell(post)
return cell
}
let cell = tableView.dequeueReusableCellWithIdentifier("IncomeExpenseCell") as! IncomeExpenseCell {
cell.configureCell(post)
return cell
}
